Definitions

  • the invention relates to an ink printing device according to the preamble of patent claim 1.
  • ink writing device To display characters or graphic patterns with an ink writing device, it is known to spray individual ink droplets from one or more nozzles of an ink print head against a recording medium.
  • ink writing devices are e.g. known from European patent specification 01 59 402.
  • Ink printing devices are known both for printing in black and white and for multi-color printing.
  • Such Ink printing device for multi-color printing of a recording medium is described, for example, in European Patent 00 21 389.
  • a predetermined number of nozzles of the ink print head is supplied with ink of the same color.
  • the inks are contained in ink containers which are arranged one behind the other perpendicular to the recording medium on the back of the ink print head.
  • the record carrier is printed line by line in a writing station and shifted between two printing processes in each case by a partial line, the width of which corresponds to the number of nozzles with the same color arranged one above the other.
  • Such ink writing heads for color printing have a large number of individual nozzles, for example 24 individual nozzles per head, which are arranged in six rows of four nozzles each. Three rows of the nozzles are used for the black and white representation and three rows for the color representation. One row prints magenta, one row yellow and one row the color cyan blue. However, it is also possible, for example, to use an ink writing head in which four rows of six nozzles are arranged. One row with 12 nozzles is used for black and white printing and three rows with 4 nozzles each for color display.
  • a printer is known in which print heads with printing elements arranged in a row with optionally different division can be used.
  • An automatic adjustment of the motor control that moves the print head in the print line direction takes place with a detection and an actuating device in such a way that the raster division predetermined by the print elements and that formed by the print head movement are coordinated with one another.
  • an ink printing device of the type mentioned with an ink printing head is known, the nozzles of which are arranged in two approximately parallel rows.
  • a delay adjustment of the triggering times for the nozzles of different nozzle rows is necessary, since the nozzle row spacings have tolerances due to production technology.
  • the similar ink print heads contain codes which represent the actual spacing of the nozzle rows.
  • a decoder evaluates the coded distance between the rows of nozzles and acts on a control device in the sense of a delay adjustment that is optimized for the printhead used in each case.
  • the object of the invention is to provide an ink printing device of the type mentioned at the outset, which makes it possible to print both in color and to produce high-quality black-and-white printing.
  • the ink print head on the printer carriage is designed to be exchangeable via a holding device, a first type of ink print heads being associated with single-color ink print and a second type of ink print heads multicolored ink printing, color printing of lower quality and black and white printing of high quality can be produced in a simple manner.
  • the invention is based on the knowledge that the same control arrangement can be used both for ink printheads with a colored impression and for ink printheads which are only suitable for black and white. You can use the hardware required for the ink head for colored printing with little software control effort to use an ink printing head for monochrome display after replacement of the ink printing head, which has a very high resolution compared to conventional ink printing heads.
  • the font quality or the writing speed can be significantly increased at a speed comparable to conventional ink printheads.
  • a coding matrix is arranged between the actual control circuit of the printing device and the replaceable ink head, which automatically links the corresponding connections to the control arrangement when changing from an ink print head of one type to an ink print head of the other type (multi-colored).
  • This coding matrix can e.g. consist of a logic circuit arrangement assigned to the ink print head or else it is designed in a simple manner as a plug connection, the individual plug contacts being connected to plug switches which close the corresponding connections when the ink head is inserted into the holding device.
  • the ink writing device according to the invention shown in FIG. 1 consists of the actual ink printing head K, which is, for example, a plastic body which contains a plurality of ink channels which end in the direction of a recording medium P on a nozzle plate DP.
  • a transducer (not shown here) is assigned to each ink channel and can be controlled in pulses by means of an electronic control ST. Depending on a drive pulse, the transducer is deformed, which leads to the ejection of a single droplet of ink.
  • the activation pulses are formed, for example, with corresponding signals which correspond to a character pattern stored in a character generator ZG.
  • the character generator contains the patterns necessary for displaying characters, which are called up in accordance with the input data ED.
  • This input data ED can also come from a keyboard TA.
  • the signals for the movement of the ink print head K and the recording medium P are also emitted via the control circuit ST.
  • two drive devices namely a first motor M1 for moving the ink print head K and a second motor M2 for moving the recording medium P.
  • the ink print head is moved line by line, that is to say horizontally, along the line over the recording medium P via the first motor M1.
  • the second motor M2 is used for line-by-line transport of the recording medium P.
  • the ink print head K is designed to be exchangeable and, with its connections A, projects into a coding matrix which acts as a coding matrix Connector strip SV. This connector strip SV is attached to a holder H of the printer carriage driven by the motor M1.
  • the ink printhead for multicolored imprint for which the control device AS is actually designed as a character generator and control device contains e.g. three rows of four individual nozzles DUE for the black-and-white impression (FIG. 3 SW) and three rows with four nozzles for color printing, one row for cyan blue Z, one row for magenta M and one row for yellow Y is provided.
  • the control device AS is actually designed as a character generator and control device
  • the ink printhead for multicolored imprint for which the control device AS is actually designed as a character generator and control device contains e.g. three rows of four individual nozzles DUE for the black-and-white impression (FIG. 3 SW) and three rows with four nozzles for color printing, one row for cyan blue Z, one row for magenta M and one row for yellow Y is provided.
  • One row with 12 nozzles is used for black and
